second embodiment
[0086] shown in FIG. 6, a monitoring system 601 of wind-induced motion or vibration according to the present invention is applied to a span of an overhead 2-bundle beam 602.
first embodiment
[0087]The monitoring system 601 comprises at least one fourth sensor node 602 adapted to be installed on at least one second overhead cable 603, in a position aligned to one of the three sensor nodes 104. The fourth sensor node 602 is thus configured to detect a motion o vibration, analogously to the first embodiment, through a synchronous signal acquisition.
[0088]Preferably, according to the second embodiment, spacers 604 are provided between the overhead cables 102 and 603, in order to reduce the risk of collisions or entanglements.
[0089]In general, the present invention provides the use of a number of sensor nodes of at least three or more, on a first overhead cable, and of at least one or more on each additional overhead cable parallel to the first overhead cable (under conditions of 2-bundle cable, 3-bundle cable, etc.). The total number of sensor nodes used mainly depends on cost criteria, keeping in mind that the present invention reaches effective results even for a reduced ...
